CHAPTER 3 LESSON 1 Flashcards
Lesson 1
is a limited capacity resource
Attention
refers to characteristics
associated with consciousness, awareness and cognitive effort.
Attention
TYPES OF ATTENTION
- Sustained attention
- Selective attention
- Alternating attention
- Divided attention
the capacity to pay attention to a single task for an extended period of time without getting sidetrack
Sustained attention
the capacity to choose from a variety of inputs and narrow your attention to one while blocking out other distractions.
Selective attention
the capacity to shift your attention between tasks that call for various levels of cognitive effort
Alternating attention
the capacity to comprehend multiple responses or respond to several demands at once
Divided attention
proposed filter theory
Broadbent
specified that we could only attend to
one input at a time.
filter theory
Attention capacity theories that propose
one source of attentional resources for
which all activities requiring attention
compete or Kahneman’s attention theory
Central-Resource Capacity Theories
There is a central pool of attention
resources, which means that there are
various attention mechanisms, each with
a finite number
Multiple Resource Theories
is the available attention that a person can give to an activity and explanation of the model
Pool of effort
examines the relationship between attention and arousal
Eysenck (1982)
the single source from which all of our
mental resources originate, and it is
flexible
Central pool
a person’s general level of excitement
Arousal
It is a span task which required them
to perform two tasks simultaneously
Dual Task Techniques
a typical experimental technique used to examine how much attention is needed to carry out an action, or part of an action.
Dual task procedure
introduced a model of attention that
introduces the idea of deliberate
allocation.
Kahneman
described attention as a reservoir of mental energy from which resources are drawn to meet situational attentional demands for task processing.
Kahneman
a reservoir of mental energy fromwhich resources are drawn to meet situational attention demands for task processing
Kahneman’s model of attention
is the directing of attention to specific characteristics in performance environment or to action preparation activities
Attentional focus
the amount of time spent concentrating on a task before becoming distracted
Attention Capacity
two types of arousal
passive system
general system
